To (Mylo/10m it may concern: v

My invention relates toimprovements in Windmills, and the elojert of theinvention is to devise a 'siu'ipleyeesy runniug'emr nple struotionotvindinill 'Whiel'r will he and eheup to eonrsitruet and it consistsentiully oili-the arrangement and eons more per tion oi parts ushereiim lter 1erly{ e-rpl eined.

The link 18 is provided inte 'n'iedietely of its lengrth with enupwardly o'lt se-tportiou The rod fad-extends freely through a lug 20*extending); from the enlargement 6'. The rod 230 extends 1| pivard andis provided at its upper end with an eye E22 through which the. shaft 52extends, ijl'it) eye 22 is normally located direeti'y above the enlargement; (5, the collar 7 being located below sue-h enlargement so as toslide ireely vertiez liy upward upon the she-it mend fromtheenlaivrenient hen the vents are set in the inoperative position oredgexvise in the Wind* the recess torn'ie'd by the (iii-set portion 19is direetly above the horizontal portion of the rod 20 so that when therod 20 is raised it enterssueh reeess -und holds the vanes definitely intheir inoperative posit-ion. In orde to ele ote the eolhr T and the rot2t) earried thereby I provide it depending rod 23 extending dtuvnvvhrdthrough the hose 1, to a suitable loeetion to be 111211 uelly operated.

When it is desired to operate tl1ewvindwill the rod is pulled downwardso as to carry the rod 20 out of the recess: formed by the oft-setportion 19. The une 141-? then swings into the Wind, that is to say, sothat the wind pressure operates; in the dime tion of arrow A. it

The vene is operetedupon hy the Wind pressure in the position shown inFin. 2, rotating the windmill in the. direction oi arrow B the vane 1dt'evelling; edgeivise against the wind until the wind pressure isexerted upon the tore thereof as it up preaches the position of the onel t illustruted in Fig.2. 2.

."v'heu it is desired to mill inoperative, the rod 20 is raised, endvrhenthe vanes some into an edgeu'iseposition with the vind the formedby the othset portion 19nssu1nes u position vertical over the horizontnlportion of therod 2i jintowhieh such rod enters. therehy looking thevanes in such positioin or the poeition render the windillustrated bydotted lines in Fig. 9, so that no driving pressure can be exerted bythe wind upon the faces of the vanes.

What I claim as my invention is:

1. In a windmill head, the combination with the main shaft and a journalsupport therefor, of an upper and lower cross arm set diametrically andmounted centrally upon the windmill shaft, a rectangular vane pivotallymounted at points adjacent its upper edge and centre upon theextremities of the aforesaid bars and at each end thereof and in such aposition as to provide a short vane arm extending in one direction, anda long vane arm extending in the opposite di rection, the 'anes beingalso set oppositely in directions one to the other, a link connectingthe long arms of the vanes together, and manually controlled means foradjusting the vanes into and out of the wind.

2. In a windmill head, the combination with the main shaft and journalsupport therefor, of an upper and lower cross arm set diametrically andmounted centrally upon the windmill shaft, a rectangular vane pivotallymounted at points adjacent its upper edge and centre, upon theextremities of the aforesaid bars and at each end thereof and in such aposition as to provide a short vane arm extending in one direction and along vane arm extending in the opposite direction. and spaced apartintermediately of the windmill vane to form an intervening openingbetween the arms, the vanes being also set oppositely in direction oneto the other, a link connecting the long arms of the vanes together, andmanually controlled means for adjusting the vanes into and out of thewind. v

3. In a windmill head, the combination with the main shaft and a journalsupport therefor, of cross arms carried centrally of their length by themain shaft, rectangular vane members swung upon the ends of the crossarms at the side of the centre remote from the windward edge, a linkconnection extending between the vanes adjacent to their windward edge,an annular collar carried by the main shaft, a pin depending downwardlyfrom the collar extending treely through an orifice in the journalsupport a rod having an annular lower portion fitting the groove of thecollar, an annular upper portion surrounding the main shaft and adaptedto be moved vertically so as to engage the recess formed by the oil-setot the link.

t. In a windmill head, the combination with the main shaft and journalsupport therefor, of an upper and lower cross arm set diametrically andmounted upon the windmill shaft, a rod bent into U shape having its baseinclined upward and having its arms extending through the cross arms ateach end at points adjacent their extremities and centre so that thelong arm of the U depends below the lower cross arm, a rectangular vanepivotally mounted upon the long arm of the U at points adjacent to theextremities of the cross arms and the lower extremity of the long arm ofthe U, and in such a position as to provide a short vane arm extendingin one direction and a long vane arm extending in the oppositedirection, the vanes being also set oppositely in direction one to theother, a link connecting the long arms of the vanes together, andmanually controlled means for adj usting the vanes into and out of thewind.
